Ultegra disc piston query

    Hi all,
    I have Ultegra R8070 discs. The front has never been easy to get just right and tends to rub. Had a good look at it this evening and have realised that the left hand piston is auto-adjusting to the space to the rotor but the right piston isn't. This means that the left pad tends to rub and also pushes the rotor over towards the right upon breaking as it has less distance to travel. My question is do both pistons normally adjust themselves to best suit the distance to the rotor or just one? Thanks!
